LTD RMG Gold carries out extraction of precious metals by using of heap leaching method in processing of secondary quartzite ore.

Heap leaching method includes processing of heap of crushed ore that is placed on the leaching field, which is covered with impassable polyethylene of high density, where ore is processed by means of low concentration cyanide solution in a closed production cycle.

It is the most widely used method of extraction of precious metals, which is distinguished by minimal negative impact on the environment and cost-efficiency. It is widely used in many countries of the world.

Method of extraction of gold by means of low concentration cyanide solution was theoretically invented in 1843 by Georgian engineer and scientist Petre Bagrationi.
